Using kdeconnect 23.0.8 on Windows 11, can input normally, and you can also use voice input on the mobile phone.

The kde connect version used by Android phones is 1.29.0

The system uses the wayland protocol.

Do you mean inputting from windows to android? Using 23.8.4 on Windows 10, I tried inputing some chinese characters with Microsoft IME and Android side could not receive it

Maybe the problem is rooted from the interaction with input method?  On Windows kdeconnect coult not handle the strings from input method.

Sorry for not describing the problem clearly.
I mean is inputting from android to Windows.
